The invention consists in elastic woven fabi f ric embodying certainprinciplesof fabricconstruction by which important advantageous resultsare attained.y

Fig. V1 of the drawings lillustrates in an opened-out state, ywith thecomponent warp" and weft elements spread apart from oneanother, aportion of webbing embodying the invention.

Fig. 2 is a view on lengthwise of the .warp threads inthe planeindicated by line 2,2, in Fig. 1, showing a rubbers-warp and threebinder warps but with gure warp threads omitted in order to illus-.trate more clearly certain features to which reference is made laterherein.

Figs. 3 and 4 are views 'in section 1n the planes which are indicated bylines 3, 3, and V4, 4,l respectively in Fig-1, with the binder warpsomitted. s

v The :illustrated fabric is composed of figure warp threads'l,'1,binder warp threads 2a, 2b, 2c, covered vrubber warp cords v8, 3,L

and form longer or shorter iioats atV the respective facesaccordingtothe'features of the design incorporated in the fabric. The iigurewarpthreads are employed singly, with a r binder separating each figurethread from those adjoining, so as to give the figure the most evendistribution possible on the face l and the back of the fabric.

.'Having reference more particularly to Fig. 2,k as will be seentherein, the binder warp always moves with the rubber., never in thecaused by running a'binder againstthe rubthe lorder of a section rubber.

ber, either whengoing up, or down, or both,l which is the usual method.With the binderlworkingl always with the rubber, it is possible to runit very tight, and it will not have the usual tendency to make Vtheupper and lower f f picks of filling cut into the covered rubber everytime the webbing is stretched. Such tendency of the binder to press thelling into Y the rubber warp lalways occurs where the binder is runagainst the rubber, and after frequent stretching of a fabric in whichsuch is the case the rubber cords will break at these places.

Changingthe binder always with the rub-kv ber allows the binder to liein a position when weaving nearer to the straight position that thevrubber takes when weaving than would be the case if the binder worked`against the In other words,`more of anobtuse langle is formed where thebinder thread bends down or up. Therefore, as well asthe binder nothaving a tendency to cut the filling into the rubber, thebinder willreach the limit and thus-put a limit on the strain to which l-`t-herubber is subjected sooner than would-be the case if the binder Vworkedagainst the rubber, either going up or going down, which lis the commonpractice when making elastic fabrics. v Y

The figure warp is run slacker than the binder warp, as indicated inFigs. 3 and 4,

namely one having more than usual warp ends y"and weft picks per squareinch. The fabric thereby, also, is rendered stronger by reason ofVcontaining more ends to resisty strain longitudinally.
